relapse vs regenerate

my ivig was recently increased to follow the recommendations I received from mayo—I too have had a lot of different feelings since this increase. My weak areas are basically my calves, ankles and feet—but I have been having strange muscle twitching, spasms,cramps in my upper legs–but am feeling stronger and fatigue is not even an issue anymore. So Im thinking—-just guessing-I am no expert, that maybe all these sensations are the nerves trying to heal,reinervation??? I actually prefer the small little aches and pains over no feeling in my calves. So hopefully the the pains are good things???? we can only hope—it does help when others share their experiences. so thank you:) Lori
